This study aimed to investigate the existence and magnitude of the association between advanced maternal age (AMA) and occurrence of placenta praevia (PP) and placental abruption (PA) among nulliparous and multiparous women, by a systematic review and meta-analysis. We searched articles published between January 1, 2005 and December 31, 2015, in any language, in the following databases: PubMed, Scopus, Web of Science, and LILACS. Women were grouped into two age categories: up to 34 years old and 35 years or older...

BACKGROUND: Maternal age at pregnancy is increasing worldwide as well as preterm birth. However, the association between prematurity and advanced maternal age remains controversial. OBJECTIVE: To evaluate the impact of maternal age on the occurrence of preterm birth after controlling for multiple known confounders in a large birth cohort. STUDY DESIGN: Retrospective cohort study using data from the QUARISMA study, a large Canadian randomized controlled trial, which collected data from 184,000 births in 32 hospitals...

Patients with total placenta previa and past history of cesarean delivery often experience overwhelming hemorrhage during childbirth. In order to control intraoperative and postoperative bleeding, we propose a novel multifaceted spiral suture of the lower uterine segment which directly sutures the bleeding site.To evaluate the efficacy and safety of multifaceted spiral suture, a retrospective study was conducted using data from 33 patients with total placenta praevia and caesarean history.All participants underwent multifaceted spiral suture and no patient experienced uncontrollable bleeding or underwent hysterectomy...

OBJECTIVE: Increased risk for adverse pregnancy outcomes with advancing maternal age has been described but the strength of association remains debated, particularly in presence of confounding factors such as parity, twin pregnancy and pregnancy from assisted reproductive technologies. The aim of this study was to evaluate pregnancy outcomes in a large cohort of women aged over 40 years. The hypothesis was that advanced maternal age may be an independent risk factor for adverse pregnancy outcome...

AIM: Postpartum haemorrhage (PPH) is one of the leading causes of maternal morbidity and mortality. Studies have reported an increase in incidence of postpartum haemorrhage in recent years. Our goal was to investigate changes in the incidence of postpartum haemorrhage (PPH) and its risk factors in Switzerland from 1993 to 2014. METHODS: This population-based retrospective cohort study used data from the national Swiss Hospital in-patient database for obstetric and gynaecological hospital admissions - "Arbeitsgemeinschaft Schweizer Frauenkliniken" (ASF Statistik)...

BACKGROUND AND OBJECTIVES: Vaginal breech delivery (VBD) is known to be associated with more perinatal and maternal complications. Very few studies on the subject have been carried out in poor-resource settings. The aim of this study was to determine maternal and neonatal outcomes in carefully selected cases of VBD for singleton term pregnancies in a tertiary centre in Cameroon. DESIGN: A retrospective cohort study. SETTING: A tertiary hospital in Yaounde, Cameroon...

OBJECTIVE: The main objective of this study is to analyse the circumstances and management of peripartum hysterectomies performed on patients with placenta percreta. METHODS: This study included 37 patients who were diagnosed with placenta percreta, a condition in which the placenta invades the uterine wall, and who therefore underwent a peripartum hysterectomy. Their demographic characteristics, history of past caesareans, uterine surgery and curettage, duration of hospitalization, admission to an intensive care unit, neonatal outcomes, skin and uterus incision type, hypogastric artery ligation (HAL), complications, quantities of transfused ES (erythrocyte suspensions), and FFP (fresh frozen plasma), maternal morbidity and mortality and postoperative pathology results were retrospectively reviewed...

BACKGROUND: Obstetric haemorrhage (OH) is the leading cause of maternal mortality worldwide, although, indirectly, HIV is also a leading cause of maternal mortality in some settings with a high HIV seroprevalence. OBJECTIVE: To determine the possible association between increasing rates of OH and HIV or its treatment. METHODS: We conducted a retrospective chart review of women with OH at King Edward VIII Hospital, Durban, South Africa, over a 3-year period (2009 - 2011), during which the drug regimen for the prevention of mother-to-child transmission was evolving from single-dose nevirapine to antenatal zidovudine combined with intrapartum nevirapine (also referred to as dual therapy), and finally to a combination or highly active antiretroviral therapy (cART or HAART)...

OBJECTIVE: Estimate the incidence of placenta accreta and describe risk factors, clinical practice and perinatal outcomes. DESIGN: Case-control study. SETTING: Sites in Australia and New Zealand with at least 50 births per year. PARTICIPANTS: Cases were women giving birth (≥20 weeks or fetus ≥400 g) who were diagnosed with placenta accreta by antenatal imaging, at operation or by pathology specimens between 2010 and 2012...

The aim of this study was to investigate the efficacy of the Bakri balloon in the management of PPH. This was a retrospective review of 49 patients, who had Bakri balloon inserted for PPH in KK Hospital between April 2013 and December 2015. The main outcome measure was achievement of haemostasis by Bakri balloon tamponade (BBT). Our success rate was 81.6%. Out of the nine failures (18.0%), five (55.6%) had subtotal hysterectomies and four (44.4%) had total hysterectomies. The causes of PPH in these nine women were unsuspected or foci of placenta accreta (55...

Endometriosis is associated with several adverse pregnancy outcomes.(1) The most severe maternal complications are spontaneous haemoperitoneum in the second half of pregnancy and placenta praevia.(1) Spontaneous haemoperitoneum, mostly associated with endometriosis infiltrating the broad and uterosacral ligaments and the Douglas pouch, is a potentially fatal but rare event. Placenta praevia is more common,(1-3) and it is important to define its incidence, the association with different lesion types, the impact of additional risk factors, the potential obstetrical consequences, and the information that women should receive...

BACKGROUND: Preterm birth is one of the biggest problems in obstetrics and gynecology, given that it has an incidence of 10-11%. The objective was to identify the risk factors associated with a preterm birth. METHODS: A retrospective, observational, transversal and analytic case-control study was made. All premature birth incidences were determined as study objects and controls were integrated with term deliveries. A sample size of 344 patients with a control per case was calculated...

Our study aimed to explore the relevant risk factors for intrauterine death of fetuses in the third trimester of pregnancy via a retrospective analysis. Then, 98 pregnant women with intrauterine death of fetuses in the third trimester of pregnancy were enrolled, who had undergone the induced labor of dead fetuses in our hospital from January, 2013 to January, 2015. By taking their disease conditions into considerations, methods of induced labor as softening of cervix with dinoprostone suppositories and amniotic infusion of ethacridine or oxytocin were performed, and the timely cesarean section for termination of pregnancy was performed...

BACKGROUND: There are few reports in the literature of the risks associated with second trimester abortion in women with placenta praevia (PP). We hypothesise that PP increases the risk of complications. AIMS: We sought to determine if PP is associated with a higher risk of blood loss and blood transfusion at the time of dilation and evacuation (D&E). MATERIALS AND METHODS: The records of 612 consecutive women undergoing abortion at 15-24 weeks of gestation were reviewed...

OBJECTIVES: The aim of the study was to identify the risk factors predisposing to morbidly adherent placenta and to study the different modes of management and the obstetric and neonatal outcome of these patients. METHODS: This was a retrospective cum prospective observational study conducted in the Department of Obstetrics and Gynaecology in a tertiary care referral hospital in Mumbai from January 2012 to November 2014. RESULTS: The incidence of morbidly adherent placenta was 1...

BACKGROUND: Twin pregnancies are at higher risks of velamentous cord insertion and vasa previa. In vitro fertilization is an additional risk factor of abnormal cord insertion and thus the incidence of vasa previa is likely to increase over the next decades. OBJECTIVE: We sought to evaluate the role of ultrasound imaging in optimizing the management of twins diagnosed with vasa previa antenatally. STUDY DESIGN: We searched our database for twin pregnancies diagnosed with vasa previa and managed antenatally using measurements of cervical length and performed a systematic review of articles that correlated prenatal diagnosis of vasa previa in twins and pregnancy outcome...

BACKGROUND: Threatened premature labor (TPL) is a severe obstetric complication which affects the mental and physical health of both the mother and fetus. Family resilience may have protective role against psychological distress in women experiencing these pregnancy complications. There may be resilience related risk factors in TPL women, and interplays may exist among psychological variables and within couples. This study aims to examine psychological outcomes influenced by different levels of resilience, and explore psychological interactions in TPL women, spouses, and between women and spouses...

Aim. To determine pregnancy and delivery outcomes among teenagers. Materials and Methods. An 8-year retrospective comparative hospital-based cohort study is analysing singleton pregnancy comorbidities and delivery parameters of a teenage group under the age of 20 compared with a young adult group 20-24 years of age in a university hospital. Results. Teenage is a risk factor for preterm birth <37 weeks (1.21 [1.08-1.35]), foetal growth restriction (1.34 [1.21-1.48]), episiotomy (1.27 [1.21-1.34]), uterine revision (1...

BACKGROUND: Maternal deaths from 'bleeding during and after caesarean section' (BDACS) have increased in South Africa, and have now become the largest sub-cause of deaths from obstetric haemorrhage. The aim of this study was to describe risk factors and causes of near-miss related to BDACS and interventions used to arrest haemorrhage and treat its effects. METHODS: Cross-sectional prospective study in 13 urban public hospitals in South Africa, from July to December 2014...
